Minecraft Non-Euclidean demonstration (Just teleports)

Made with simple teleport and player detection commands. You can test it out yourself here. It may be laggy on bad computers though.

This is definately not a new concept, it is just a simple demonstration.
Notes:
The current version of minecraft recorded with has a new glitch where the teleporting is not seamless, which is why the hand shifts around during teleports. While not visible this video makes use of 3 teleports, but only the first one is significant.

NPCs can not path-find through these "portals" and act like they are not there, but they can still be teleported through them.

The map should be able to work in multiplayer, however you will see the other player teleport away and only appear when you have gone through the "portal" too.

The building shown at the beginning is the smallest size you can have for a vanilla non-euclidean illusion. Any smaller building will, as far as I've tested, break the illusion. You also can not have an illusion without a corner, sadly. The initial and final place must, from the point of teleportation, have the exact same shape, blocks and lighting for the illusion to work. It also works to have "buffer" zones where a teleport can be set at each end.

Feel free to go into spectator mode to see how it all fits together, or rather, doesn't.
